Here is the set up I just settled on:
Late 2009 Mac Mini (Snow Leopard, 120GB SSD, 8GB RAM) with external 1TB HD connected via FireWire>Audiophilleo1 with Pure Power>Lessloss DAC 2004 MkII. Alternately I eliminate the Audiophilleo and run USB direct into a Resolution Audio Cantata (dealer disclaimer). I use Audirvana for playback (iTunes integrated mode and turn off all iTunes controls so you are just using the interface) and the remote app for iPad to access my music library.
I also configured the Mac Mini using a guide published by Larry Moore. For more information I would suggest going to the Empirical Audio site and looking at some of the tips and system recommendations there.
